1. The structure of the ice maker-The ice maker mainly consists of compressor, filter dryer, condenser, expansion valve, evaporator, electric box, one-way valve and other components:

2. The compressor, which provides power for the ice machine, is the heart of the ice machine. The quality of the compressor is one of the important indicators for evaluating the quality of the ice machine.

3. Dry filter, which function cannot be underestimated, it can filter the moisture and residue of the ice making system, it is the scavenger of the ice machine, and guarantees the stable operation of ice making.

3. Condenser. There are two types of condensers, air-cooled and water-cooled. Air-cooled mainly rely on fans to remove excess heat and cool the high-temperature vapor refrigerant into a liquid state to provide the necessary temperature for the ice maker to evaporate.

4. Expansion valve. The ice maker usually uses a thermal expansion valve. Its function is to throttle and expand the liquid refrigerant into a vapor refrigerant, provide conditions for the ice maker to evaporate, and adjust the flow of the ice maker’s refrigerant.

5. Evaporator, ice maker evaporator is commonly known as ice bucket. Its main function is to absorb the heat of water and quickly freeze the water. Whether an ice machine manufacturer can produce an evaporator is a symbol of the strength of the ice machine manufacturer.

6. Electric box, usually the electric box will be input to the control system, and each component has been controlled to coordinate and operate stably. Usually there are multiple relays, contactors, PLC controllers, and phase sequence protectors. The assembled electrical box is much better than the circuit board, the system is stable, safer, more reliable, convenient for maintenance, and the disadvantages are slightly more expensive.

a. Other components, such as one-way valve, prevent the refrigerant from flowing back and out, solenoid valve, control the refrigerant flow rate and pressure of the ice making system, etc.

b. Remarks: The structure of the large ice maker is slightly different, and there will be more accessories.

Second, the working principle of the ice maker

Take the flake ice machine as an example. The evaporator is a device for making flake ice. It is cylindrical and has a ring-shaped deflector ring inside to quickly exchange cold and heat with water (water evenly sprinkled from the water trap). The ice is quickly connected, and the reducer drives the ice skates to hang the ice down and drop it into the ice storage bucket.
